NFC is a short-range wireless technology that allows data exchange between electronic devices within 20 centimeters. It uses magnetic field induction and operates at 13.56 MHz. For two devices to communicate using NFC, one must have an NFC reader/writer and the other an NFC tag. NFC is expected to be included in one in five phones by 2013 and enable uses like downloading content, exchanging contact cards, and mobile payments at point-of-sale terminals. The NFC Forum is working to expand the NFC ecosystem through education, research projects, and industry partnerships.
